WASHIBOILER.

Specification of Letters Patent.

PatentedMar. 2, 1915.

Application filed December 7, 1914. Serial No. 875,871.

To all whom it may concern Be it known that I, ALBERT A. Former, acitizen of the United States, residing at Kansas City, in the county ofJackson and State of Missouri, have invented a certain new and usefulImprovement in Washboilers, of which the following is a specification.

This invention relates to improvements in wash boilers.

It relates particularly to the type of wash boilers provided with apressure chamber from which water is projected by steam pressure intothe upper portion of the boiler upon the clothes therein contained.

One of the objects of my invention is to provide a boiler of this typewhich is of simple construction, which may be readily cleaned, and whichwill be eflicient in operation.

A further object of my invention is to provide novel means by which thewater utilized for washing the clothes will be automatically filteredand freed from dirt prior to its being discharged upon the clothescontained in the boiler.

Other novel features of my invention are hereinafter fully described andclaimed.

In the accompanying drawings, which illustrate the preferred embodimentof my invention, Figure 1 is a vertical sectional view on the line 1-1of Fig. 2. Fig. 2 is a topview of my improved boiler. Fig. 3 is a crosssection on the line 3-3 of Fig. 2.

Similar reference characters designate similar parts in the differentviews.

1 designates the body of the boiler, which may be of any suitable shape,and which has mounted in it an inverted pan-shaped bottom member 2, thetop of which is provided with one or more upwardly extending annularflanges 3, which are externally screwthreaded and have detachablyrespectively fitted thereto inverted cup-shaped members 4. The upper endof each cup-shaped member 4 is provided with one or more dischargeopenings 5. Upwardly and outwardly in clined discharge openings 6 mayalso be provided in the side wall of each member 4 above the flange 3.The top of the member 2 within those portions encircled by the flanges 3are provided each with one or more discharge openings 7. Filteringmaterial 8 is provided in the members 4.

Two T-shaped discharge conductors have their lower ends 9 respectivelydetachably fitted in two vertical screw-threaded holes provided in thetop of the member 2 adjacent to the ends thereof. The horizontal portion10 of each of said T-shaped members, on its inner side is providedwithdischarge openings 11. The top of the member 2 is provided with adownwardly extending tubular portion 12 having a perforated bottom 13.Contained in the tubular portion 12 is filtering material 14, which isreleasably held therein by means of a horizontally slidable perforatedremovable cover 15, which is slidably mounted in grooves provided belowtwo parallel flanges 16, with which the upper side of the member 2 isprovided. To the top of the member 2 is secured a handle 17 by means ofwhich the false bottom member 2 may be removed from the boiler body 1.

In the operation of my invention, water having been placed in the boilerand the clothes to be washed disposed in the washing chamber, which isthat portion above the false bottom member 2, the water is heated to aboiling temperature, thereby creating steam and forming a pressure inthe pressure chamber, which is that portion embraced by the bottommember 2. The pressure formed in the pressure chamber will force thewater therefrom upwardly out of the T-shaped conductors 9-10 and uponthe clothes, the density with which the filtering material 8 is packedin the cup-v shaped members 4 permitting of an accumulation of pressuresufficient to cause the water to be projected from the openings 11 withconsiderable force. Water will also be discharged, as will some of thesteam through the discharge openings 5 and 6 in the members 4. The dirtywater from the washing chamber will return to the pressure chamberthrough the perforated cover 15, filtering material 14, and perforatedbottom 13. Most of the dirt will be eliminated from thereturn water andwill be held by the filtering material 14. Any dirty water passingthrough the openings 7 from the pressure chamber will be cleansed bypassing through the filtering material 8. For holding the false'bottommember 2 in position during the operation of the boiler, any suitablereleasable means may be provided. In the drawing I have shown for thispurpose, a spring plate 18, Fig. 3, the lower end of which is secured tothe inner and lower portion of one side of the body 1, and the upper endof which is provided with an inwardly extending hook portion 19, whichis adapted to engage the upper side of the member 2, when the latter isin its operative position at the bottom of the One side of the bottommember 2 boiler. may beprovidedwith a vertical channel 20 for receivingthe spring plate 18, which serves as a catch which will automaticallylook when the bottom member 2 is slid down wardly into position. Afterthe washing has been completed and the clothes and water emptied fromthe boiler, the false bottom member 2 may be released from the catchplate 18 and removed from the boiler. The cup-shaped members 4 may thenbe unscrewed and deta'chedfrom the flanges 3 so as to permit thefiltering material?) to be removed and cleansed. lhe perforated cover 15may be moved to the open position and the filtering material 1% thenremoved from the tubular portion or receptacle 12 for the purp'ose ofcleansing said'material. The filtering material 8' and 14: may befibrous asbestos, cotton, or any other suitable substance, I v

I do not limit my invention to the structure shown and described, asmodifications, within the scope of the appended claims, maybe madewithout departing from the spirit of my invention.

1. A wash boiler having a washing chamber and apressurje chamber belowthe washing chamber, the pressure chamber having an inlet, and a noutlet communicating with. the washing chamber, said inlet comprising acup shaped portion having a bottom opening, a perforated cover for saidinlet adapted to be moved to the open or to the closed position, andfiltering material in said cupshaped portion. p

2. A wash boiler having a washing chamher and a pressure chamber belowthe washing chamber, the pressure chamber having a discharge opening inits upper side and provided with an annular flange encircling saidopening and provided with an inlet communicating with the washingchamber, a cup-shaped member having a discharge opening communicatingwith the washing chamber and provided with ascr'ew-threaded engagementwith said annular flange, and filtering material in said inlet and insaid cup-shaped member. v, I

3. Awash boiler having a washing chamber and a pressure chamber belowthe washing chamber, the pressure chamber having an inlet and anoutlet'communicating with said washing chamber, discharge conductorcommunicating withsaid pres'su're chamber and discharging into thewashing cham ber at a point higher than the p'oint of discharge of saidoutlet, and lilterin'g material. in said outlet, the capacity for thedischarge of water through said outlet with the filtering materialtherein being sul'liciently restricted topermit the pressure in thepressure chamber to force water therefrom through said dischargeconductor into said washing chamber. J i p In testimony whereof I havesigned my name to this specification in presence O'f two subscribingwitnesses. v
